cds-question@unistra.freclipsing-binary-starsasteroseismologyvisible-astronomyEclipsing double-lined spectroscopic binaries (SB2s) hosting delta Scuti-type pulsators offer a unique laboratory for simultaneously constraining stellar geometry and interior structure. In this study, we present a comprehensive analysis of five oscillating eclipsing Algol (oEA) binaries. By combining high-precision, short-cadence TESS photometry with multi-epoch high-resolution spectroscopy, we derive precise stellar and orbital parameters. Frequency power spectra were obtained using residuals from binary modelling. We further investigate the evolutionary history of these systems using a grid of MESA binary evolution simulations. Our analysis suggests that the systems must have undergone either case A or case B mass transfer, with the primary components repositioned in the Hertzsprung-Russell diagram and now pulsating in the delta Scuti regime, while the cooler secondaries are underluminous and inflated, filling their Roche lobes. This study contributes to the growing catalog of well-characterised oEA systems and our understanding of the effects of mass-transfer on the fate of these short-period binaries.2026A&A...705A.251Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/705/A251CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/705/A251https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/705/A251http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/705/A251https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/705/A251https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/705/A251http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/705/A251GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/705/A251/table1 (Basic information about the targets)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/705/A251/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/705/A251/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/705/A251/table1?GETtext/xml+votable180.050000true235.69835111-57.5109480.0055555555555555566/17953 22753 39272 41797 467533.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/705/A251?format=asciiOpticaldefaultJ/A+A/705/A251/table1Basic information about the targetsrecnoRecord number assigned by the VizieR team.
